The Bosch Rexroth ZDR10DA2-5X/150Y (R900410884) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predetermined setting value. This direct-operated spool valve is part of the ZDR series and comes equipped with a mechanical actuation mechanism. It provides precise control in applications requiring pressure limitation in the secondary circuit.
The valve features a size 10 interface, with a maximum operating pressure of 315 bar and can handle a maximum flow of 150 l/min. Its construction includes a housing, control spool, compression spring, and an adjustment type, along with an optional check valve for free flow back from channel A to A in version A. The pressure adjustment range can be set via the adjustment type which includes options such as a rotary knob or sleeve with hexagon and protective cap.
This model's versatility is highlighted by its multiple versions (A, P, B), each tailored for specific circuit requirements. Version A allows hydraulic fluid to flow unrestricted from channel A to channel A when in the initial position. The secondary pressure is regulated through an internal control line that balances the system against external forces.
For different configurations, version P focuses on reducing pressure in channel P, while version B reduces pressure in channel P but sources pilot oil from channel B. The importance of correct port connections is emphasized when using this valve without a directional valve or when setting up with a directional seat valve.
The Bosch Rexroth ZDR10DA2-5X/150Y also features connection diagrams compliant with NFPA T3.5.1 R2-2002 D03 and ISO 4401 Size 6 standards. Its design incorporates NBR seals suitable for various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC types. With its robust build and precise control capabilities, this sandwich plate valve is essential for efficient hydraulic system management where regulated secondary pressures are critical.

The valve type ZDR is a direct operated pressure reducing valve in sandwich plate design with pressure limitation of the secondary circuit. It is used to reduce the system pressure.
The pressure reducing valve basically comprises housing (1), control spool (2), compression spring (3), adjustment type (4) and an optional check valve.
The secondary pressure is set via the adjustment type (4).
Version “A”
The valve is open in initial position. Hydraulic fluid can flow from channel A➀ to channel A➀ without restrictions. The pressure in channel A➀ is simultaneously applied via the control line (5) at the piston area opposite the compression spring (3). If the pressure in channel A➀ exceeds the value set at the compression spring (3), the control spool (2) is pushed against the compression spring (3) to control position and keeps the set pressure in channel A➀ at a constant level.
Control signal and pilot oil are supplied internally via the control line (5) from channel A➀.
If the pressure in channel A➀ increases further due to an external force effect at the actuator, it pushes the control spool (2) even further against the compression spring (3).
In this way, channel A➀ is connected to the tank (channel TB) via the control edge (6) at the control spool (2) and the housing (1). So much hydraulic fluid is discharged into the tank, that the pressure does not increase any further.
The leakage oil drain from the spring chamber (7) is always effected externally via channel TA.
A pressure gauge connection (8) allows for the control of the secondary pressure at the valve.
A check valve can be used for free flow back from channel A➀ to A➀ with version “A”.
Versions “P” and “B”
For version “P”, the pressure reduction is effected in channel P➀. Control signal and pilot oil are supplied internally from channel P➀.
For version “B”, the pressure is reduced in channel P➀; but the pilot oil is extracted from channel B. If the directional valve is in spool position P to A, the pressure in channel B may not exceed the set secondary pressure. Otherwise, there is pressure reduction in channel A.
Attention!
If used without directional valve, channels TA and TB are connected to each other (e. g. in the cover plate). During set-up of a directional seat valve NG 10, a sandwich plate type HSZ10A078-3X/M00 (material no. R900537264) has to be used.Type ZDR 10 DA …
